Résumé

The impact of selective cutting (6 and 8 years after treatment) and strip clear-cutting (12 and 13 years after treatment) on abundance and diversity of carabid beetles was evaluated in a northern hardwood forest of Quebec, Canada. A total of 1078 individuals belonging to 14 species were captured with pitfall traps from June to September 1996 during 2568 day-trap. Abundance of Synuchus impunctatus Say was significantly higher in clear-cut compared with uncut control strips. There were no within-species differences between selectively cut and uncut plots. None of these two silvicultural systems had any significant impacts on species diversity and richness 6-13 years after treatment. Although we observed an effect of strip clear-cutting on the abundance of S. impunctatus in this northern hardwood forest, the discrepancy between the response of carabids to forest disturbance in this study compared with other studies in different ecological regions suggests that the same carabid beetle species cannot be used as an indicator of forest disturbance over a large region. Our results suggest the use of carabid beetles as a disturbance indicator at the ecological-type scale (relatively similar soil and forest type) in a given region.
